I was on the website today and prices are

Race Prepped .21= 369.99
Extech .21=339.99
Fully Modded=419.99

Is the big boy pipe worth getting over the tuned truggy pipe. I have a friend telling me not to get the big boy. I am ordering the .24 race prepped extech for my K8T truggy and cannot decide on the pipe. The big boy looks wierd and unlike anything I have seen.

Hi all
What size carburettor Venturis can you get for a 2008 Extech .21 motor.

Regards
Gary

Who do I contact about my big boy pipe?
The baffle came loose today.

Dayton

Can someone post up the rear bearing size? I see where sirio rears are 14.2x25.3 but wasn't sure if this was the same.

That is the bearing size for the extech 2. I just replaced mine.

Ran the FM .24 today with od77t plug and 2035 pipe. Wow great combo. Killer power down low and great top. Hits the powerband real smooth. Getting around 10 with temp 210-220. Really coming alive at just about 1.5 gallons. Idles all day with loading up too much either. New favorite plug. No more 10$ P4's

Ran my fully modded Extech .21 today even though I did not plan on it. My other motor I was trying had something go bad in it so had to throw the new extech in. I know they are ran a little before we get them so I only got to run a half tank before my B-main. Running at 185 and rich as hell I bumped and had the fastest lap times from any truggy out there all day! Ran the A still really rich and had 1.5 laps on the field but had a cvd pin fail. Replaced that and got out back out there 10 laps down on a 30 minute main and ran down the others and finished 4th. Motor was 205 and still really rich but still FAST! Cannot wait till its fully broken in!

how much better is the fully modded one over the regular extech?? And how does the stock extech compare to the vspec? How long will it last (well roughly) and is it a sensitive tunning?

Hello, I ripped the carb boot on my extech today. Does anyone know where to buy one from? A-main doesn't sell them. thanks
